3 Claims.

This invention relates to new and useful improvements in a dispensing device for pastes and fluids such as tooth paste, shaving cream, etc.

At the present time due to war conditions the available supply of collapsible tubes generally used to hold and dispense tooth pastes, shaving cream, and the like is becoming scarce. This invention contemplates a dispensing container which may be repeatedly refilled and re-used and which may effectively dispense tooth paste, shaving cream, and the like. The new dispensing devices makes no use of tin or other pliable collapsible metals.

The invention contemplates characterizing the dispensing device by a jar for holding the paste or fluid, and a piston within the jar normally adjacent its bottom wall and slidable so that it may be moved upwards and associated with a manually controlled mechanism for moving thepiston upwards to dispense the tooth paste, shaving cream or the like, as required.

The invention contemplates providing the jar with a cover having a discharge opening through which the paste or fluids are dispensed.

Still further a novel arrangement of auxiliary piston is proposed by which small controlled amounts of the material may be easily dispensed.

For further comprehension of this invention, and of the objects and advantages thereof, refer ence will be had to the following description and accompanying drawing, and to the appended. claims in which the variou novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 6 is a fragmentary sectional View taken on the line 6-45 of Fig. 5.

Fig. 7 is a fragmentary sectional view taken on the line 1-1 of Fig. 4.

Fig. 8 is a similar view to Fig. l. but showing a further modification of the invention.

The dispensing device for pastes and fluids such as tooth paste, shaving cream, etc, in accordance with this invention, includes a jar ID for holding the tooth paste, shaving cream or the like. A piston II is located within the jar Ill and is norm-ally disposed adjacent the bottom wall of the jar and is slidable so that it may be moved upwards.

Means is provided for non-rotatively holding said piston. This means consists of a vertical bead 12 extended along the inner side oi the jar l0 and engaging a complementary groove l3 formed upon one side of said piston I l.

The jar H] is normally closed by a cover 14 which is shown provided with a skirt wall l5 threadedly engaged upon the top of the jar l0. This cover 64 has a discharge it at one side. This discharge i6 connects with a groove I! extended along the bottom face of the cover M. A screw B8 is rotatively mounted on the cover I 4 and extends downwards through the jar I0 and is threadedly connected with the piston H for raising the piston.

The screw iii is arranged coaxially of the jar H5 which is of cylindrical form. The top end of the screw I 8 is provided with a knob l 9 located upon the outside of th cover M by which it may be turned. A washer 28 is fixed upon the screw l8 immediately beneath the bottom face of the cover !4 for rotatively holding the screw It. This screw has a sharp pitch, as schematically indicated in Fig. 2. The bottom end of the screw 18 a reduced section 2| which engages into a socket in a boss 22 formed on the bottom wall of the jar Iii. The arrangement is such thatthe cover I may be removed and then the reduced end will merely lift away from the boss 22. v

The operation of the device is as follows:

The cover It may be removed. The piston H may then be unscrewed from the screw I 8 and dropped into the bottom of the jar Ill. The jar in may then be filled with tooth paste, shaving cream or the like. The cover M is then replaced on the jar Ill and the screw I8 is turned so that its threads threadedly engage the piston H.

Then the knob It may be slowly turned as reovired to cause the piston I! to move upwards, which indirectly forces out some of the-tooth pa te or shaving cream through the discharge 1 5.

In the modified form of the invention illustrated in Figs. 4-7 inclusive, the cover 14' for the dispensing device is provided with a downwardly extending chamber 25 on its bottom face. This chamber extends into the top of the jar I0. An auxiliary piston. 26 is located in the top of the chamber 25. Means is provided for manually depressing this auxiliary piston 25 to discharge some of the tooth paste, shaving cream or the like from the jar l through the discharge l6.

.More specifically, the auxiliary piston 26 is fixedly mounted upon the bottom of a stem 27 which extend through a tube 23 slidably mounted through the cover I l. The outer end of the stem 21 is provided with a head 29 by which the stem may be moved. A pin 30 from the tube 28 engages in a bayonet slot 3! formed in the side of the stem 21 by which the stem 21, and thus the piston 26, may be fixed in a relatively raised or lowered position relative to the tube 28.

A handle 32 is provided with a forked end 33 having a trunnion 3i pivotally engaging a ring '35 rotative on the screw IS. The handle 32 also is provided with an opening 35 through which the tube 28 projects. A trunnion 3i from the sides of the tube '38 engages elongated slots 33 formed in the sides of the handle 32. An expansion spring '39.acts between the cover it and the handle 32 for normally urging the tube 28 outwards. flange 4!) formed on the inner end of the tube 23 engages the top wall of the chamber 25 and limits outward extension of the tube 28.

In other respects this form of the invention is similar to the previous form and like parts are identified by like reference numerals.

The operation of this form of the invention is as follows:

The knob It may be turned for causing the piston II to move upwards to dispense the tooth paste, shaving cream, etc. or to get ready to dispense these ingredients. Then the handle 32 may be pressed downwards a distance required so that the auxiliary piston 25 will be correspondingly moved which will act against the tooth paste, shaving cream, or the like to actually dispense it through the discharge I 5. After the handle '32 has been fully depressed it is possible to dispense an additional quantity of tooth paste, shaving cream or the like by moving the piston 26 downwards relative to the tube 28. To do this the head 29 is turned so that pin 39 engages the vertical portion of the bayonet slot 3! Then the stem 2'! may be moved downwards. The head 29 is again turned to look the stem 2'! in its lowered position. The handle 32 may now be manipulated to dispense additional tooth paste or shaving cream from the jar Hi. When no more can be dispensed then the knob 55 must be turned to cause the piston i l to move upwards and resupply the chamber 25 with tooth paste, etc.

In Fig. 8, the operating knob i9 is shown projecting from the bottom surface til of the jar ill, for rotating the screw H and the discharge nozzle I6 is shown with a swivel type of spout I5 for permitting the contents of the jar is to be discharged in various directions. In other respects, this form of the invention is similar to the previous forms. 1

It is to be understood that the jar It may be cylindrical, conical, or of any other desired shape.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
